The invention relates to a subscription session state control method oriented to a mobile production management terminal page. The method comprises the following steps that the controllers of multiple clients send heartbeat access to a server every application module of every client with valid access submits subscription application to the server, and the control module of every client with the valid access submits subscription determination application to the server after the clients submit subscription requests to the server through subscription interfaces, the server establishes the subscription state objects of the clients in a subscription state object pool the server corrects the subscription state objects in the subscription state object pool according to the subscription determination application received by the subscription determination interfaces and corrects determined object subscription states into subscribing states the server executes a subscription publishing process on the subscription state objects with the subscribing state in the subscription state object pool. According to the subscription session state control method oriented to the mobile production management terminal page, the validity of the subscription session of a client is determined through the online signals of the server, and invalid sessions are removed timely, so that garbage memory generation can be avoided, and the service efficiency provided by the server can be maintained.
